Yellow-rumped Warblers in Arizona

Yellow-rumped Warblers live in Arizona all year. Low deserts stay mild and host many wintering sparrows and hummingbirds; the high country gets snow. That makes the cold months the time your yard matters most to them: their winter diet shifts toward bayberry, wax myrtle and juniper fruit.

Hot Sonoran and Mojave deserts in the south and west, with pine-oak sky islands and the Colorado Plateau rising above 7,000 ft.

Across Arizona, yellow-rumped warblers typically nest from April–July. Nest site: cup on a horizontal conifer branch. Females lay 1–6 eggs, incubate for 12–13 days, and young leave the nest after 10–14 days.

Summer highs above 110°F in Phoenix and Tucson make water the single strongest attractant; the July monsoon triggers a second breeding pulse.

• Yellow-rumped Warblers don't use nest boxes. Keep dense native shrubs and trees such as smooth sumac, black cherry, american elderberry for nest sites.
• Delay heavy pruning of shrubs until after July.
